Question

I know this question has with out any doubt been asked a whole lot of times. I though can seem to find a solution. So forgive me if it’s way to simple.

The question is how do access the end of a while loop.

E.g.

    while($countByMonth = mysql_fetch_array($countByMonthSet)) { 
            $c = $countByMonth["COUNT(id)"];
            echo $c . "," ; 
        }

How do I manage separate each value of the while loop by a comma but of course I don’t want the comma at the end of the value.

In advance thank you very much for your help 🙂

You can:

1) Build a string, and remove the last character:

$c = '';
while ($countByMonth = mysql_fetch_array($countByMonthSet)) { 
    $c .= $countByMonth["COUNT(id)"] . ',';
}

$c = substr($c, 0, -1);
echo $c;

2) Build an array and use implode()

$c = array();
while ($countByMonth = mysql_fetch_array($countByMonthSet)) { 
    $c[] = $countByMonth["COUNT(id)"];
}

echo implode(',', $c);

Tip: You can use aliases in your query, like: SELECT COUNT(id) as count FROM .... Then you can access it as $countByMonth['count'], which looks cleaner IMO.
